Я попытался просмотреть свои XML-файлы, а также проверить все мои зависимости. Но я пока не смог точно определить, что не так.

Это сборка Gradle.

Сводка ошибок приведена внизу.

Вы используете dependencies из androidx, поэтому вам нужно использовать com.google.android.material.bottomnavigation.BottomNavigationView

Используйте это 

<com.google.android.material.bottomnavigation.BottomNavigationView 
     android:id="@+id/bottom_navigation"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     app:menu="@menu/bottomnav"
     app:itemBackground="@color/colorPrimary"
     app:itemIconTint="@android:color/white"
     app:itemTextColor="@android:color/white" />

Вместо этого 

<android.support.design.widget.BottomNavigationView
     android:id="@+id/bottom_navigation"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     app:menu="@menu/bottomnav"
     app:itemBackground="@color/colorPrimary"
     app:itemIconTint="@android:color/white"
     app:itemTextColor="@android:color/white" />
...
